NI sent out a survey for feedback on the original KORE. Since people weren't using the built-in audio interface they ditched it in version 2. I have the original KORE hardware, although I might put it up on Ebay.
I should point out that the K2 has jacks for foot pedal switches. You'll notice the K1 has knobs on the front panel for audio levels and the K2 doesn't.
Nope, it's a Kore 1 - the Kore 2 didn't have the knobs at the top. Or if it did, they forgot to put them on the one I have in front of me!! Mike
